Studio's D and E are primarily designed for composition, mixing and mastering in a multi-channel sound field and are identical to each other with several important differences.  They are also used occassionally for simple recording tasks and various research experiments, and are located in the Knoll Room 221 and 320 (behind the Classroom and Stage) respectively.

As with any of the Studio's please don't unplug or repatch any of the studio equipment.  Also refrain from eating and drinking in the studios.  Reserve the rooms with the CCRMA Room Booking System

See the attached pdf files below for current studio operations and Quick Start Guides!

Monitor Level Calibration

The monitoring level is calibrated. With a standard signal and standard routing and levels you should get about the same SPL readings on all studios. For details on how and why to do this see this very good article:


Settings used for calibration as follows:
  • pink noise output level in Digital Audio Workstation (Logic, Ardour, etc): 0dB in a K14 meter (-14 dB re: full scale)
  • master level in DM1000: -10dB (blue reference lines)
  • individual channel level in DM1000: -5dB
With those settings we calibrated the SPL level at the center of the room (C curve, slow setting) to about 78dB. As we have set the channel fader to -5dB this is almost a SMPTE20 calibration. Please do NOT change the volume at the speaker, adjust SPL levels in your mix or in the DM1000 digital mixer.

Calibration dates:

Studio E: March 24 2016
Studio D:

Laptop Station

Each studio has an audio interface to connect your laptop to the system (specfically to the mixer).
